Anything can be sold on eBay these days. Some items like a $5 oil can ok not worth your time listing it. eBay charges 10% fee on the sale price. I called a local gold dealer and asked him what he paid for gold and he said spot prices minus a dollar or two and 10% less than that. I said why 10% less? He said, because it would cost you 10% to sell it on eBay. (Even though I'm not doing that here).
So moral of the story. It costs money to sell stuff, I mean just the regular folks that have the stuff, not a business like Pickers. It takes effort as well. Someone shows up and offers you cash and takes care of everything is worth something. Staged or not it's a really good show.
